98 Octane

[Ward P]

Can't say I've noticed any difference between 95 and 98 on the bike, but it pings its head off with 91. The bike is a "toy", so I try to avoid anything but 98.

BUT . . .There's a big red sticker inside my car's filler cap that sayes "98 min".
On testing I've found no noticable difference so I run 91 most of the time. Doesn't ping, no real appreciable power difference, and no fuel economy difference. I do lots of miles, so it makes a huge cost difference on a full tank of fuel though.
And I laugh at the people putting 98 in their 'standard' cars.
